Porsche Doppelkupplung (PDK)<br />
The Porsche Doppelkupplung (PDK) is a sevenspeed<br />
transmission with an “automatic” and a<br />
“manual” selection mode.<br />
In automatic selection mode (selector lever<br />
position D), gear changing is automatic.<br />
You can change temporarily from automatic to<br />
manual mode using the shift buttons on the<br />
steering wheel.<br />
In manual selection mode (selector lever<br />
position M), you change gear using the shift<br />
buttons on the steering wheel or with the PDK<br />
selector lever.<br />
You can change between selector lever position D<br />
and M as you wish while driving.<br />
Note<br />
f Take care not to operate the shift buttons on<br />
the steering wheel inadvertently in either<br />
automatic or manual mode, thereby triggering<br />
undesired gear changes.<br />
178 Shifting Gears<br />
Changing the selector lever position<br />
The selector lever is locked when the ignition is<br />
switched off.<br />
When the ignition is switched on, the selector lever<br />
can be moved from position P and N only when<br />
the release button is pressed, and when the brake<br />
pedal is pressed.<br />
Release button<br />
The release button (arrow) in the selector lever<br />
prevents the gear from being changed unintentionally.<br />
The release button must be pressed when shifting<br />
to position R or P.<br />
Starting<br />
The engine can be started only if the brake<br />
pedal is depressed and the selector lever is in<br />
position P or N.<br />
Driving off<br />
f Only select the desired position for driving off<br />
(D, M or R) when the engine is idling and the<br />
brake pedal is depressed.<br />
f Since the vehicle creeps when in gear, do not<br />
release the brake until you want to move off.<br />
f After selecting a gear, do not accelerate until<br />
you can feel that the gear is engaged.<br />
Driving off on hills<br />
The Drive-Off Assistant assists the driver when<br />
moving off on hills. The vehicle is held on the slope<br />
for a short time during the change from the brake<br />
pedal to the accelerator in order to allow driving<br />
off directly after the brake is released.<br />

TANT” on Page 177.
